If you have MUBI, watch the Spanish series ‘The New Years’. It’s the best thing I have watched on TV for a long time. Worth signing up to MUBI to binge it.

I avoid centripetal because in my experience students put in an extra phantom force and when I ask what that force is, they reply it’s the centripetal force. Likewise centrifugal.

Teacher prep day sounds like a good idea!

For anyone interested in history/WW2 or stories of real people going through extraordinary times, sometimes shocking and often moving, this is a fantastic book. Just finished it but going to call it one of my favourite reads in 2025.

Great book!

The new Edexcel poster is good on command words qualifications.pearson.com/content/dam/...

Edexcel FM1 is terribly dull, focusing on impact and impulse, but FM2 is great. And you can’t do the latter without the former. But overall that would be my pick for both students and staff.
A head of maths at a top RG uni once told me: the more pure and mechanics the better.

@mrsmaths.bsky.social My students have been working their way though your further maths practice core pure papers as a revision (double) lesson before their mocks. Absolutely brilliant questions: thank you so much.

Yes, very!

I do maclaurin expansions first and then show how the expansions of cosx +isinx is the same as the expansion of e^(ix).

Hang in there. You can do it.

In #MathsToday I gave my further #ALevelMaths students a vectors worksheet to do as revision for forthcoming mocks.
I accidentally used a set of questions they had previously done as homework but no one noticed!

Okay thanks

Is that still the assembly point? Hasn’t the march been re-routed?

Got it! It looks great, even more useful than the first book.

Just finished the fourth and last episode of Trespasses on Channel 4. Excellent. I recommend it.

Yeah, I have the other one, but I need to get off my butt and buy this one too!

Apart from madasmaths, where is the best place to find very hard exam-style questions for (Edexcel) Further Maths?

@andrewhickey.500songs.com Interesting documentary last night on Sky Arts ‘I was a teenage Sex Pistol’, Glen Matlock’s story. A lot of talking heads and clips. A well done, informative and entertaining story. Still available on catch up.

This may have come up before but is is arccotx or arcotx?

They play a different set each time so I think going three times is not at at all extreme. Glad to hear you are a GW fan.

And breathe

Great, thanks

Thank you. I didn’t think to look in the F/b, duh.

I am teaching differentiation practical problems at the moment and wondering which area/volume formulae students need to know. For example, surface area of a cone? Is there a list somewhere of assumed knowledge for #AlevelMaths ?
#MathsToday

Haha, nice distinction

I gave my Y12 students a test today in #ALevelMaths . They complained afterwards that they didn’t know what a rhombus is.
I don’t teach GCSE: would you not expect students to know what a rhombus is at GCSE?

Don’t you hate it when a student asks for help with part (iv) of a STEP question?

I recommend this movie. Thrilling and funny and entertaining. And incredible soundtrack.
